Extensional viscosity aspects of HPAM in porous flow: An experimental and numerical study

Polymer flooding is the most widely used chemical EOR method. Despite being widely used, the apparent shear-thickening behaviour of the polymer solutions in porous flow at high flow rates is poorly understood. One of the supposed mechanisms is the strain-thickening behaviour of polymer solutions. This fluid property will alter the flow dynamics...

Pressure Behaviour and Fracture Development during Polymer Injection in a Heavy Oil Saturated Unconsolidated Sand

Polymer flooding is an important EOR method in heavy oil reservoirs, where field studies showed a recovery up to 59%. However, accurate assessment of injectivity of viscous polymer solutions can give major challenges. Little research has been devoted to pressure build-up phenomena with polymer injection in porous media. Therefore, the objective...
